Hi Team,  
Greetings..! Hope you are safe and good in health.  
I want to reindex data of index 'A', from cluster 'X' to cluster 'Y'. I have whitelisted the 'X' cluster host in cluster 'Y' using reindex.remote.whitelist: in all elastic nodes.  
But I got "message": "Client request timeout" as message.  
Configuration details:  
Cluster X: Version:7.2.1,  
Nodes count:5 data & 3 master  
Cluster Y: Version:7.2.1,  
Nodes count: 3 data/master nodes(no dedicated master node).

Kindly help me to reindex data from one cluster to another cluster.

POST \_reindex  
{  
"source": {  
"remote": {  
"host": "X cluster host and ip",  
"username": "user",  
"password": "pass"  
},  
"index": "source",  
"query": {  
"match": {  
"test": "data"  
}  
}  
},  
"dest": {  
"index": "dest"  
}  
}  
Thanks in advance.

Regards,  
Gokul
